Where in Elixir's documentation is the method to call Erlang code described?

You can call functions in Erlang modules by prepending a colon:

:erlang.time()

...but where is this notation described in the Elixir reference documentation?

I ask because I'd prefer to use the straight docs to master Elixir, but I apparently need some initial bootstrapping information to understand how critical bits are organized.

This information is well known, but it's not mentioned in the reference documentation, where you have purely Elixir-specific stuff.

Just check the official introduction to Elixir. The most valid part of it for you is:

Note. Since Erlang modules are represented by atoms, you may invoke Erlang functions in Elixir as follows:

:lists.sort [3, 2, 1]

All of the Erlang built-ins reside in the :erlang module.

I don't think it's stated directly. The name of each Erlang module is an atom. Prefacing a string with a colon indicates the string is an atom. :Module. function simply resolves to a specific function in a module in Erlang.
